Abstract (en)

[origin: WO2016102572A1] The invention relates to a power split gearbox (30) for a motor vehicle. The power split gearbox (30) comprises a drive shaft (12) which can be connected to an internal combustion engine (14) in order to feed in torque, a first mechanical branch (16) with a planetary gear mechanism arrangement (18), an infinitely variable second branch (22) which can be connected to the first branch (16) and comprises two adjustable energy converters (H1, H2) which can be coupled to one another in energy terms and can be operated in each case in both directions, and at least one output shaft (24) which can be coupled to the drive shaft (12) via the first and the second branch (22). At least one first reversing stage (32) is provided between the drive shaft (12) and the output shaft (24) for changing between at least one first forward driving range and at least one first reverse driving range, wherein the reversing stage (32) either reverses or keeps constant all of the rotational directions of the sun gears (Z1, Z1'), the internal gear (Z3) and the spider shaft (20) during changing between the first forward driving range and the first reverse driving range.
